SLP400 Jonas Nick & Tim Ruffing - Half Signature Aggregation: What is it and how does it help scale Bitcoin?

Jonas Nick & Tim Ruffing, bitcoin researchers and contributors at Blockstream rejoin me on the show, this time to chat about half signature aggregation. This is a scaling technique that can help scale Bitcoin and enable more transactions inside a block or help with L2 protocols. We discuss:

  • How this idea came to be
  • What is half aggregation vs ‘full aggregation’?
  • What kind of savings are possible?
  • What are the downsides?
  • How would this work in practice?
  • Is a soft fork required?
  • Next steps for discussion, research, contributors
